HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: D

Rationale: The correct answer is D: weight at birth. LBW stands for Low Birth Weight, which is a crucial indicator of an infant's health and development. Monitoring a baby's weight at birth is essential for assessing growth and identifying potential health issues. The other choices are incorrect because A (genetic makeup) is not typically abbreviated as LBW, B (feeding schedule) is unrelated to birth weight, and C (Babinski response) is a neurological reflex test, not related to weight at birth.

Correct Answer: C

Rationale: The correct answer is C: full. Replete means filled or well-supplied with something. In this context, it refers to being completely full or satisfied. Choice A (hardy) does not convey the same meaning. Choice B (quiet) and choice D (sad) are unrelated to the definition of replete, making them incorrect. Therefore, C is the best fit as it directly aligns with the definition of the word.

Correct Answer: C

Rationale: The correct answer is C: Gums and teeth. When people masticate, they use their gums to hold the food in place and their teeth to break down the food into smaller pieces through chewing. This process is essential for digestion. Choices A, B, and D are incorrect because fingers, eyes, ears, heels, and toes are not involved in the mastication process.

Correct Answer: C

Rationale: The correct answer is C, at the pinnacle of success. "Zenith" means the highest point or peak, so being at the zenith of your career implies reaching the highest level of success. Choice A is incorrect as it suggests being at the beginning, which contradicts the meaning of zenith. Choice B is incorrect as it implies preparing to end one's career, which is the opposite of being at the peak. Choice D is incorrect as it suggests facing challenges with superiors, which is not necessarily related to being at the peak of success. Therefore, the best answer is C, as it aligns with the meaning of "zenith" in the context of a career.
